Zuul在SpringBoot 2.7和Java11中有任何支持问题吗？

Question

我正试图在我的SpringBoot Gradle项目中实现Zuul。我在运行应用程序时遇到了一些问题，我已经尝试了几乎所有可以在网上找到的方法。有人知道这里出了什么问题吗？

这是我的Gradle构建文件

    plugins {
        id 'org.springframework.boot' version '2.7.1'
        id 'io.spring.dependency-management' version '1.0.11.RELEASE'
        id 'java'
    }
    
    group = 'com.zuul'
    version = '0.0.1-SNAPSHOT'
    sourceCompatibility = '11'
    
    repositories {
        mavenCentral()
    }
    
    dependencies {
        implementation 'org.springframework.boot:spring-boot-starter-web'
        implementation 'org.springframework.cloud:spring-cloud-starter-netflix-zuul:2.2.10.RELEASE'
// implementation group: 'org.springframework.cloud', name: 'spring-cloud-starter-zuul', version: '1.4.7.RELEASE'
        testImplementation 'org.springframework.boot:spring-boot-starter-test'
    
    }
    
    tasks.named('test') {
        useJUnitPlatform()
    }

启动应用程序时遇到的错误

Answer 1

Spring是Spring版本的最后一部分，它与SpringBoot2.2和2.3兼容，随后的版本删除了对Netflix库的大部分支持(如宣布的这里，更多信息这里)，如发布说明中提到的那样。

因此，不会与Spring 2.7一起工作，因为Spring版本严格地绑定到特定的Spring版本。

相反，您应该在Spring中使用新的网关支持，而不是Zuul。
